According tothe present invention in a squeeze roller-apparatus, one of-'a pair of cooperating.

squeeze rollers is carriedby blocks mountedin slideblockswwhichslideblocks are displaceableitowards and -away from-the otherotsaid-"pair of squeeze rollers whereby to vary the minimum clearancebetween said rollers, said blocks being slidably mounted in saidslideblocks and resiliently urged towards the said other of said pair ofsqueeze rollers, and adjustable stop devices being provided intermediatethe slideblocks and the blocks whereby to vary the maximum clearancebetween said squeeze rollers.

The slideblocks are suitably displaceable by means of a manuallyrotatable wheel carried on the frame of the apparatus.

The adjustable stop devices suitably include threaded stop memberscarried by the slideblocks and displaceable relative to the slideblocksand relative to the blocks by means of a manually rotatable wheelcarried on the slideblocks.

A locking pin carried by a slideblock is preferably displaceable from aninoperative position to an operative position to lock the blockassociated therewith.

The invention is further described by way of example with reference tothe accompanying drawings, in which:

Fig. 1 is a side elevation, partly in section, of an apparatus accordingto the present invention, and

Fig. 2 is a corresponding end view.

In the drawing an upper squeeze roller II is mounted above a lowersqueeze roller [2. The rollers are operatively connected by known means(not shown) to rotate the same. The upper squeeze roller is carried atone end by a block 13 slidably mounted in vertical guides in an upperroller slideblock 14. The upper roller slideblock I4 is itself slidablymounted in vertical guides in the frame 15 of the squeeze rollerapparatus.

The vertical position of the upper roller slideblock [4 is adjustable bymeans of handwheel (not shown) on shaft I6. A bevel pinion H on shaft I6is in engagement with a bevel wheel [8 carried at one end of a threadedmember I9 ro- ,tatably. oonnectedltoitherfi'ame ;-l 5.

will be seen that the tension of the spring 20 may be adjusted by meansof the collar 24a.

A lever 25 is pivotably connected at its upper end to the slideblock. Alocking pin 26 (shown in the locked position) is pivotably connected tothe lever 25 and passes through projections from the slideblock l4 and adownwardly extending part l3a of the block [3. The lever 25 is pivotableby a foot-pedal (not shown) to displace the pin 26 into and out of thelocked position.

It will be seen that the handwheel on shaft 16 controls the minimumclearance between the squeeze rollers ll, I2, and that the handwheel 23controls the maximum clearance between the squeeze rollers ll, l2.

Both handwheels may be readily operated during operation of theapparatus.

It will be appreciated that whereas only a single lever 25, locking pin26 and associated parts are shown, the block 13, slideblock l4 and partsassociated therewith will be duplicated at the other side of thisapparatus.

An apparatus according to the present invention may suitably comprise adough break.

In order to reduce in thickness a slab of material (e. g. a slab ofdough), the minimum and maximum clearances between the squeeze rollersare set by means of hand wheels I6 and 23 and the locking pin 26 isdisplaced out of the locked position. The slab of material is passed oneor more times between the squeeze rollers, the weight of the uppersqueeze roller H and the force of the springs 20 causing a reduction inthickness of the slab. As soon as the slab has been reduced toapproximately the thickness of said minimum clearance, the pin 26 isdisplaced into the locked position to lock the squeeze rollers at saidminimum clearance. A subsequent final passage of the slab between thesqueeze rollers accordingly ensures uniform reduction in the thicknessof the slab.

I claim:
